Upvote for the comment, but the reality is OOP (at least in C++) encourages people to write code this way. When you have a sufficiently large code base and an unforeseen requirement comes in, one that wasn't planned for in those architectural committees, you have a problem. And that problem is solved by either a man-century of refactoring, or by taking some shortcuts that destroy the purity of the code and eventually lead to these monstrous god objects that you mentioned. This happens over and over, to the point where you can't just say "oh it was an accident, happened just one time".
